We do not know when man first began to use salt,but we do know that it has been used in many different ways throughout history.Historical evidence shows that people who lived over 3,000 years ago ate salted fish.Thousands of years ago in Egypt,salt was used to preserve the dead.
In Roman Empire,one of the most important roads was the one that carried salt from the salt mines to Rome.In the early days in the United States,salt was very scarce.So,the storekeeper then was very careful with his salt.As he poured out salt for a customer,he did not like anyone to walk across the floor of the store.The walking might shake the floor and could cause the salt to "settle"and as a result the storekeeper would have to add a little more salt to the amount he had already poured out.
